We have a bad kettle… it has been designed poorly. When we boil some water and it’s almost at 100 degrees lets say to save time/energy you pick it up before it has “clicked off” because the water is hot enough anyway.. You pour your required amount of water and put the electric kettle back in its holder and it continues right where it left off… wasting electricity trying to boil the rest of the remaining (if not empty) water… this kind of issue is something small but how hard can it be to discontinue an interrupted process. It would save energy even 🙂
